+300°C Radial Lead Coated / Uncoated Class II/COG
25 Vdc to 4.0 KVdc

300C Multilayer ceramic capacitors - Radial Lead - Coated Eclipse NanoMed manufactures  a  line  of  +300°C  High  Temperature Radial Leaded COG / Class II ceramic capacitors, which are intended for those applications where there may be concerns over exposure to thermal and  /  or  mechanical  shock  during  a  typical  installation  process  or operating conditions.
These capacitors incorporate our leading edge dielectric materials and are manufactured  using  a  proprietary  high  temperature  lead  attach  process that  can  withstand  continuous  exposure  to  temperatures  in  excess  of  +300°C.
300C Multilayer ceramic capacitors - Radial Lead - Uncoated
Utilized in distributed power systems intended for the harsh environments associated  with  the  aerospace  and  automotive  engine  compartments typical  applications  for  X7R  capacitors  include  decoupling,  by-pass, filtering,  transient  voltage   suppression,    blocking   and   energy   storage.    COG  /  NPO   capacitor  applications  include  precision  timing  circuits,  RF oscillators   and   other   precision   circuitry   requiring   low   loss and    stable  performance.
