ICP-S
1. Overview
The ICP-S is an IC protector of surface mounting type developed as an element for the protection of ICs from output
short-circuiting damage. The internal resistance of this lightweight, compact overcurrent protection element is low, as long
as the steady-state current of the element does not exceed the rated DC or AC current. The ICP-S, however, turns off ICs
instantly if the steady-state current reaches or exceeds the breaking current of the ICP-S.

3. Features
1) Instantly breaks currents with a low potential drop.
2) Compact surface-mounting model.
(See 3-1 Potential Drop Comparison)
(See 2. External Dimensions)
3) Unlike fuses, there is no steady-state current reduction with the rated current applied. No derating is necessary.
4) Minimal breaking point dispersion.
(See the graph in 3-2 Breaking Current Dispersion
Characteristics)
