RSBIC2100AA00K KEMET 0.01µF 250V Film Capacitor

ElecSuppliers Part Number GuideAug 22, 2026

RSBIC2100AA00K is a KEMET RSB series metallized polyester film capacitor designed for automotive and general-purpose electronic applications. It provides a capacitance of 0.01 µF, a capacitance tolerance of ±10% and a rated DC voltage of 250 V.

The capacitor uses a radial leaded construction with a 5 mm lead spacing. Its compact stacked-film structure makes it suitable for PCB designs where a stable film capacitor is required without using a much larger conventional film capacitor.

RSBIC2100AA00K Key Specifications

RSBIC2100AA00K has a nominal capacitance of 0.01 µF, equivalent to 10 nF or 10,000 pF. The capacitance tolerance is ±10%, while the rated voltage is 250 VDC. The component also has a 160 VAC rating.

The capacitor uses a metallized polyester film dielectric and a radial box-style construction. Its lead spacing is 5 mm, with an approximate body length of 7.2 mm, height of 6.5 mm and thickness of 2.5 mm.

The specified operating temperature range extends from -55°C to +125°C. The rated temperature is 85°C, and the component is qualified to AEC-Q200 requirements.

KEMET RSB Film Capacitor

The RSB series is designed around a stacked metallized polyester film construction. Compared with ceramic capacitors, film capacitors can provide useful characteristics for applications where capacitance stability, insulation performance and controlled dielectric behavior are important.

The metallized film construction also supports a compact component format. RSBIC2100AA00K combines this construction with a relatively small radial package, making it practical for PCB applications where a through-hole film capacitor is preferred.

The RSB series includes different capacitance and voltage combinations, so the complete part number should be checked when selecting a component. Similar RSB part numbers can have different voltage ratings or capacitance values even when their physical appearance is similar.

RSBIC2100AA00K Automotive Qualification

One of the important characteristics of RSBIC2100AA00K is its AEC-Q200 qualification. This makes the component relevant to automotive electronic designs where passive components need to meet automotive qualification requirements.

Automotive electronic systems use film capacitors in power conversion, filtering, control electronics and other circuits. The wide operating temperature range of the RSB series also provides flexibility for equipment exposed to significant temperature changes.

AEC-Q200 qualification does not mean that the capacitor is automatically suitable for every automotive application. Engineers still need to evaluate voltage stress, temperature, mechanical conditions, ripple current and the actual electrical environment of the application.

RSBIC2100AA00K Applications

RSBIC2100AA00K can be used in a variety of electronic circuits requiring a 10 nF film capacitor with a 250 VDC rating.

Potential applications include automotive electronics, industrial control equipment, power supplies, filtering circuits, signal coupling and general-purpose DC applications.

The relatively small capacitance value makes the component suitable for circuits where 10 nF is required for filtering, suppression or signal-related functions. The actual application should be determined from the circuit's electrical requirements rather than from the capacitance value alone.

RSBIC2100AA00K Package and PCB Mounting

RSBIC2100AA00K uses a radial through-hole package with a 5 mm lead pitch. The two leads are positioned for direct PCB insertion, making the component compatible with conventional through-hole assembly processes.

The approximately 7.2 mm × 6.5 mm × 2.5 mm body provides a relatively compact footprint for a film capacitor. This can be useful in automotive control boards and industrial electronics where through-hole film capacitors are still preferred for particular circuit functions.

The PCB layout should account for the component body dimensions and lead spacing. Mechanical clearance should also be considered when the capacitor is installed close to heatsinks, connectors or other tall components.

RSBIC2100AA00K Electrical Design Considerations

When using RSBIC2100AA00K, designers should consider both the DC voltage and the AC voltage applied to the capacitor.

The 250 VDC rating should not be interpreted as a universal operating limit under all conditions. AC operation, temperature, transient voltage and circuit frequency can affect the actual electrical stress on the component.

The datasheet also specifies voltage derating above the rated temperature. For the RSB series, the available voltage decreases as the temperature rises above 85°C, so thermal conditions should be included in the design calculation.

For automotive applications, engineers should additionally consider vibration, thermal cycling and long-term reliability requirements when placing the capacitor on the PCB.

RSBIC2100AA00K Replacement Considerations

When replacing RSBIC2100AA00K, the replacement should match the basic capacitance, voltage rating and tolerance requirements.

The dielectric type and qualification are also important. Replacing an AEC-Q200 film capacitor with a general-purpose capacitor that has the same 0.01 µF capacitance does not necessarily provide equivalent reliability or environmental performance.

The lead spacing and physical dimensions should be checked as well. A 5 mm lead pitch is part of the mechanical specification of this component, so a replacement with a different pitch may require PCB modification.

KEMET's RSB family contains closely related part numbers with different voltage ratings, capacitance values and packaging options. The complete MPN should therefore be retained when sourcing an exact replacement.

RSBIC2100AA00K Availability

RSBIC2100AA00K continues to be listed by major electronic component distributors. Current element14 listings identify the exact KEMET part number and show AEC-Q200 qualification, RoHS compliance and the 0.01 µF, 250 V film capacitor configuration.

Current distributor information also shows that availability is more limited than for many high-volume general-purpose capacitors. Mouser currently lists the exact part as non-stocked with a factory lead time of about 33 weeks, while element14 shows a manufacturer lead time of approximately 24 weeks in some regions.

This makes current lead-time verification important when RSBIC2100AA00K is being considered for production procurement.

RSBIC2100AA00K for Automotive and Industrial Electronics

RSBIC2100AA00K combines a 0.01 µF capacitance value, 250 VDC rating, ±10% tolerance, radial through-hole construction and AEC-Q200 qualification in a compact KEMET RSB series package.

Its automotive qualification and wide temperature range make it particularly relevant to automotive and industrial electronics where passive components must withstand demanding operating conditions.

For new designs, engineers should evaluate the capacitor together with the complete circuit voltage, temperature and frequency environment. For replacement applications, matching the complete RSBIC2100AA00K specification is important to maintain both electrical performance and mechanical compatibility.
