Paktron Capstick Series (CS11)

Paktron's CS11 is a high-voltage Capstick stacked metallized polyester capacitor designed for high ripple current, high capacitance density, and low-loss high-frequency performance in a rugged package. It extends the Capstick family into 1000 VDC and 1200 VDC ratings while offering thru-hole, SMD gull-wing, and SMD J-lead configurations. The series combines ultra-low ESR/ESL, self-healing behavior, and lightweight construction compared with equivalent MLCC solutions.

Key features

• Type: Multilayer Polymer (MLP) Film
• Grade: Hi-Rel/ Rugged/High Voltage
