ESP H Series
TSC-0912 - 09.10.12
Technical specification
For some data and signal applications with lower current, higher in-line resistance or higher bandwidth requirements, the ESP D or E Series
protectors or the Slim Line ESP SL Series may be more suitable. If the protector is to be mounted directly onto a PCB, use the ESP PCB/**D or
ESP PCB/**E protectors.

1 Nominal voltage (DC or AC peak) measured at < 10 µA
(ESP 15H, ESP 30H, ESP 50H, ESP 110H) and < 200 µA
(ESP 06H).
2 Maximum working voltage (DC or AC peak) measured at
< 5 mA leakage (ESP 15H, ESP 30H, ESP 50H, ESP 110H) and
< 10 mA (ESP 06H).
3 The maximum transient voltage let-through of the protector
throughout the test (±10%), line to line & line to earth, both
polarities. Response time < 10 ns.
