In a move to meet the demands for performance and reliability in automotive and industrial systems, Vishay has extended the capabilities of its 140 CRH series of surface-mount aluminium capacitors to offer very high capacitance values and ripple currents.
A polarised aluminium electrolytic capacitor with a non-solid, self-healing electrolyte, the 140 CRH is ideally suited for filtering, smoothing, buffering and voltage decoupling applications in automotive and industrial systems for high ambient temperatures up to 125°C.
Offering enhanced performance and reliability, the devices feature a capacitance range of 10 μF to 1000 μF over a voltage range of 6,3 V to 63 V, a high ripple current up to 900 mA at 100 kHz/125°C, and ESR down to 90 m² at 100 kHz. The capacitors are available in five case sizes, ranging from 8 x 8 x 10 mm to 12,5 x 12,5 x 16 mm.
For high vibration capability, 140 CRH capacitors with 12,5 mm diameters are available in 4-pin versions, with 4-pin versions of 10 mm devices available on request. The capacitors feature a long life up to 3000 hours at +125°C. The RoHS-compliant devices are charge- and discharge-proof, so there is no peak current limitation. The capacitors operate over a broad temperature range from
