DESCRIPTION

These thermistors are made of NTC ceramic material. The

device consists of a chip with two tinned nickel leads. The

parts are coated and color band marked. Tape and reel

versions available on request.

PACKAGING

The thermistors are packed in cardboard boxes; the

smallest packing quantity is 500 units.

MARKING

The thermistors are marked with color bands on a gray

epoxy base coating; see Dimensions and “Electrical Data

and Ordering Information”.

MOUNTING

Important mounting and handling instructions: see

www.vishay.com/doc?29222

By soldering in any position. Not intended for potting.

Notes

Preferred versions for new designs
