Capacitor targets fast-switching converters

The SMT CeraLink snubber and DC link capacitor (B58031I5105M002) features low 3.5 nH equivalent series inductance and a 500 V DC rating. The device has a 1 µF typical nominal capacitance and operating temperature of -40° to +125°C.

The 10.8 x 7.8 x 4.25 mm capacitors ESR is 12 mΩ at 1 MHz and 3.3 Ω at 1 KHz. It uses a RoHS-compatible PLZT ceramic and costs approximately $11.50 ea/1,000. A second SMT version has a 5 µF value and a larger through-hole version is available with a 20 µF value.
