FEATURES
• Same materials and construction as the
non-hermetic MIL-PRF-55182 resistors
• 100 % stabilization and screening tests.
Undergoes group A testing to MIL-PRF-55182
(thermal shock, 1 h overload, short time
overload, DC resistance) prior to shipping.
• Very low noise (-40 dB)
• Controlled temperature coefficient
• Epoxy coating provides superior moisture protection
• Standard lead is solderable and weldable
• Traceability of materials and processing
• Vishay Dale has complete capability to develop specific
reliability programs designed to customer requirements
• Material categorization: for definitions of compliance

MATERIAL SPECIFICATIONS
Element
Vacuum-deposited nickel-chrome alloy
Core
Fire-cleaned high purity ceramic
Encapsulation
Specially formulated epoxy compound
Termination
Standard lead material is solder-coated
copper. Solderable and weldable per
MIL-STD-1276, type C
Revision: 16-Sep-16
POWER RATING
Power ratings are based on the following two conditions:
1. ± 2.0 % maximum R in 10 000 h load life
2. +175 °C maximum operating temperature
APPLICABLE MIL-SPECIFICATIONS
MIL-PRF-55182:
With the exception of the MIL spec’s 3 % lead (Pb)
requirement, the industrial ERC series would meet the
electrical, environmental and dimensional requirements of
MIL-PRF-55182.
