In free air, THS3 Series exhibit a case temperature rise of approximately 20˚C per watt dissipated.
Capacitor Life
Capacitor Life
THS3 Series capacitors are rated for >2,000 hours at 85°C and rated voltage or 125°C at de-rated voltage. The effective life of a capacitor in a given application is based on the specific operating voltage and average temperature.
THS3 Series Capacitors have an unlimited Shelf life.
All THS3 ratings are RoHS 9/10 compliant to EU RoHS Directive 2011/65/EU.
Negative terminal is 60/40 SnPb plated copper wire
Positive Terminal is 60/40 SnPb plated Nickel Tube
Handling Guidelines
Handling Guidelines
Attachment / Mounting by leads only is discouraged in applications exposed to mechanical shock or vibration. Always ensure capacitor is firmly secured to PWB, by either mounting studs, epoxy staking or both (preferred for vibration environments).
Provide adequate care to protect the Glass to Metal Seal (GTMS)
Avoid forces on the positive terminal, lateral, axial or torque.
Avoid mechanical shock to the positive terminal.
Secure the part to PWB before soldering
Mounting with studs
#2-56 CDA-752 studs are available as a standard option.
Use spacers (provided) to fill the gap between PWB and leaded surface of capacitor.
Tighten Studs to 30-40 in-oz.
Secure nuts (provided) with red Loctite. Do not use lock washers.
Potting / Epoxy Staking
We advise epoxy staking capacitor to PWB even when using studs, for maximum vibration tolerance.
In some applications it may be advisable to pot the cavity between the PWB and leaded surface.
Highest shock/vibration applications may require the capacitor to be fully potted.
Soldering
Rim of Capacitor is intended to mate directly to PWB. Advise using no-clean flux.
Utilize ANSI J-STD 001 Standard Through Hole Soldering methods.
Lead trimming
Provide adequate care if leads must be trimmed.
Trimming the positive terminal is not recommended.
Lead lengths available in 1/32” increments from 0.125” when measured from the rim of the capacitor.
