Type CB Capstick High Frequency Switching Power Supply Capacitor
The CB style capstick capacitor is constructed non-inductively
with metallized polyester dielectric. The low inductance and
low ESR construction makes it ideal for high frequency switching
power supplies. CB type capacitors can be used with pick and
place assembly and the -FS parts are fully RoHS compliant and
capable of high temperature lead free soldering.
- Low Impedance construction
- Self healing
- Low ESR/ESL
- Flat Surface for pick and place
- Surface mount
- High Ripple current/High capacitance
