PMR205 Datasheet, PDF (1/2 Pages) List of Unclassifed Manufacturers – RC unit, metallized paper with integrated resistor

PMR205
• RC unit, metallized paper with integrated resistor
• 0.1 – 1.0 µF, 22 - 680 Ω, 125 VAC, +85 °C
• Small dimensions
• High dU/dt capability.
• Excellent self-healing properties.
Ensures long life even when subjected to
frequent overvoltages.
• 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.

The series resistance is defined at 1 kHz for RC ≥ 50 µs
and at 100 kHz for RC < 50 µs.
≥ 3000 MΩ for C ≤ 0.33 µF
≥ 1000 s for C > 0.33 µF
Measured at 100 VDC after 60 s, +23°C
The average losses may reach 0.5 W provided the
surface temperature does not exceed + 85°C. For
maximum permitted power dissipation v temperature,
