PMR209
• RC unit, class X2, metallized paper with integrated resistor
• 0.047 – 0.47 µF, 22 – 470 Ω, 250 VAC, +85 °C
• Small dimensions
• Excellent self-healing properties.
Ensures long life even when subjected to
frequent overvoltages.
• High dU/dt capability.
• Self-extinguishing encapsulation.
• Good resistance to ionisation due
to impregnated dielectric.
• The impregnated paper ensures
excellent stability giving outstanding
reliability properties, especially in
applications having continuous operation.
TYPICAL APPLICATIONS
CONSTRUCTION
RC unit for use in DC and AC applications
for:
– contact protection
– interference suppression of contacts
– transient suppression
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.

Power ratings
The 100% screening factory test is carried out at 1800
VDC. The voltage level is selected to meet the requirements
in applicable equipment standards. All electrical
characteristics are checked after the test.
Recommended voltage ≤ 630 VDC.
The average losses may reach 0.5 W provided the surface
temperature does not exceed + 85°C. For max. permitted
power dissipation vs temperature, see derating curves.
