PMR205
鈥?RC unit, metallized paper with integrated resistor
鈥?0.1 鈥?1.0 碌F, 22 - 680
鈩?/div>
, 125 VAC, +85 擄C
鈥?Small dimensions
鈥?High dU/dt capability.
鈥?Excellent self-healing properties.
Ensures long life even when subjected to
frequent overvoltages.
鈥?Self-extinguishing encapsulation.
鈥?Good resistance to ionisation due
to impregnated dielectric.
鈥?The impregnated paper ensures
excellent stability giving outstanding
reliability properties, especially in
applications having continuous operation.
L
TYPICAL APPLICATIONS
RC unit for use in DC and AC applications
for:
鈥?contact protection
鈥?interference suppression of contacts
鈥?transient suppression
B
CONSTRUCTION
Single layer metallized paper. Encapsulated
and impregnated in self-extinguishing
material meeting the requirements of UL
94V-0. The resistance in the metal layer is
utilized as series resistance, integrated
resistor.
