A and B types are designed for high reliability and efficiency these resistors are outstanding in their high-
power dissipation with precision tolerances as well as their transient absorption capabilities.
The very high performance Type B subminiature axial resistors for Exceptional Power to Size Ratios and
employ Solid Beryllium or Alumina cores.
Both A and B styles provide SUPERB RELIABILITY and ultra-stable performance under the most rigorous of
operating conditions.
Both types have high transient over load capacity and can be specifically optimized for pulse applications.
Their precision, all welded construction results in exceptional strength, stability, and reliability even under the
most demanding, and extreme conditions. Pacific manufactures it's resistors in America under Mil-Spec
Quality Control conditions. Resistors are available in any resistance value up to the maximum listed.
Far Superior Pulse and High Temperature Tolerances to Film Resistors, which require massive
amounts of heat sinking and low Temperatures to prevent self-destruction.
The availability of Non-Inductive and RoHS compliant styles, combined with Pacific Resistor’s fast deliveries
on a vast choice of resistance values and tolerances adds up to increased flexibility for our customers.
