Specification

Please note that all parameters can not necessarily be specified in the same device

The ACT1x5, 2x6 & 3x8 are miniature cylindrical packages offering high vibration and shock resistance,

together with high stability. They are suitable for portable equipment and where a close packing density is

required.Two versions are offered, C1BLC: a low cost version and the HQM4E: a version with a higher Q

value. The 1x5 device is only available in the High Q version.

Soldering

Lead wires should be soldered within 10

seconds with a tip temperature not exceeding

270°C.

The device should ideally be upright on the

board.

If the device can is required to be mechanically

affixed to the board it should be stuck down

with rubber adhesive.

Under no circumstances should any solder

connection be made to the can of the device.
