THQS2

Evans Capacitor Company THQS2 Series Capacitors

Product Overview

The THQS2 series capacitor shall utilize sintered tantalum anodes and ruthenium oxide coated cathodes operating in aqueous electrolyte with additives. The components shall be hermetically sealed in a welded tantalum case with a glass-to-metal anode terminal seal.

The THQS2 capacitor comes in a 0.6” round diameter case. These capacitors are perfectly suited for applications with high impact shock requirements. Applications are limited cycle, limited time on change, such as missile fusing and short duration power hold up. THQS2 capacitors have impact shock capability of 30.000g and higher.

Environmental Compliance

THQS2 Series are RoHS 9/10 compliant to EU RoHS Directive 2015/863.

The standard terminals are 60/40 SnPb plated Nickel Wire
RoHS compliant Lead free leads available. See part numbering nomenclature for ordering info

Handling Guidelines

Attachment /Mounting by leads only is not allowed. Always ensure capacitor is firmly secured to PWB.

Provide adequate care to protect the Glass to Metal Seal (GTMS)

Avoid Forces on the (+) pin, lateral, axial or torque.
Avoid Mechanical Shock of any kind to the pin.
Secure the part to PWB before soldering

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. Positive terminal can not be trimmed below the nickel lead (0.167 from rim).
