TDK CGA2B3X7R1E104K 0.1uF 25V X7R 10% 0402 Automotive Ceramic Capacitor 130 PCS

TDK CGA2B3X7R1E104K automotive-grade multilayer ceramic chip capacitor rated 0.1 uF / 100 nF, 25 VDC, ±10% tolerance, with X7R dielectric in the compact 0402 / 1005 metric surface-mount package.

This device belongs to TDK’s CGA automotive-grade MLCC family and is AEC-Q200 qualified for demanding environments. It is suitable for decoupling, bypassing, filtering, power-rail stabilization, automotive control electronics, communications equipment, industrial electronics, embedded systems, and general high-reliability PCB applications.

TDK specifies 100 nF capacitance, 25 VDC rating, X7R temperature characteristic, -55°C to +125°C operating range, and 0402 / 1005 package size for this family. :chatgpt-content-reference{index="0"}

Original Mouser packaging identifies the TDK CGA2B3X7R1E104K family, 0402 package, 25 VDC, 0.1 uF, country of origin Japan, and date code 1939.

Lifecycle: ACTIVE.

HISTORICAL BACKGROUND: TDK was founded in Japan in 1935 as Tokyo Denki Kagaku Kogyo and grew into one of the world’s major manufacturers of passive electronic components, magnetic materials, sensors, capacitors, inductors, and electronic materials.

The CGA series was developed specifically for automotive-grade multilayer ceramic capacitor applications. Compared with ordinary commercial MLCC families, automotive-grade parts undergo additional qualification intended for environments where temperature cycling, vibration, humidity, and long service life are significant concerns.

The 0402 / 1005 metric package measures approximately 1.0 x 0.5 mm and allows high component density while keeping connection lengths short. This is especially useful for local decoupling and high-frequency power-rail suppression close to integrated circuits.

X7R dielectric is a Class II ceramic material designed to maintain capacitance within approximately ±15% across a temperature range of -55°C to +125°C. This combination of temperature capability and high capacitance density makes X7R one of the most widely used dielectrics for decoupling and filtering.

The 0.1 uF value became one of the standard decoupling values in modern electronics. Capacitors of this value are commonly placed directly across IC power pins to reduce switching noise and stabilize local supply voltage.

TDK currently lists the corresponding CGA2B3X7R1E104K050BB production version as active and AEC-Q200 qualified, confirming that this remains a current automotive-grade capacitor family rather than obsolete stock. :chatgpt-content-reference{index="1"}
