Jermyn Semiconductor Hardware

Jermyn Manufacturing is synonymous with making transistor clips and mounting pads (stand offs), to the sound of Beatles music, in the early nineteen-sixties. By the mid-seventies they had increased the offering to include sockets, heatsinks and other associated semiconductor accessories. Winslow bought the rights to the Jermyn Manufacturing portfolio in 1984, inheriting tooling, drawings and production jigs Today, we still produce these products using the original die sets and drawings, the only manufacturer in the world to be doing so.

Mounting Pads

Providing mechanical support to the device, insulation between device and PCB, minimise thermal shock during soldering. Many convert one pin configuration to another, often to a larger pitch (PCD) or spread leads for easy connection and soldering.

Case Style TO18

Case Style TO5

Case Style TO5 Multilead

Case Style TO92/98 Lead Formers

Transitor & Circular IC Sockets

Incorporating Pin 1 identification and countersunk lead-ins for easy device insertion, having the outside edge of the contact external to the plastic body aids in-situ testing from the top.

8 Pin TO-99 Transistor Socket

3 Pin TO39 Transistor Socket

3 Pin TO18 Transistor Socket

Opto/Diode Display Sockets

Specifically designed to accept 7 segment displays, allowing packages to be mounted side by side or end to end.

Insulators, Panel Washers, Bushes, and Covers

Providing mechanical protection for chassis and panels against the action of screws, protecting devices from shorting.

Insulating Bush

Cover

Component Carrier

Designed to support mechanically a wide range of axial components in either a horizontal or vertical mode. They provide protection from soldering temperatures and short circuits from adjacent components.

Heatsinks

A heat dissipater that operates as a result of the temperature difference and thermal resistances between the heat source (semiconductor) and the ambient air. The heat sink increases the surface area available for heat transfer from the semiconductor thus increasing the amount of heat that can be dissipated. The amount of heat that can be removed is most often characterised by thermal resistance i.e. the lower the thermal resistance the better the performance. The only way thermal resistance can be reduced is by either increasing the physical size of the heat sink i.e. changing the surface area or by moving more air across the sink (changing from natural to forced convection coefficients, typically a fan or blower).

Mounting & Insulating Kits

Mounting & Insulating Kits for mounting power transistors to heatsinks where insulation is required

TO-220 Heatsink Transistor Mount Kit

W7700 Series Ribbon Wrap

Flat Cable Clamps used to attach flat cables to surfaces thereby solving flat cable routing problems. Up to eight cables 0.89mm (0.035") thick can be held by a single clamp which locks with plastic ratchet strips, keeping the cables secure. They feature a simple, one-handed release. Fix to a suitable surface with rivets, bolts, screws or adhesive pads.
