AW56GKE Datasheet, PDF (1/1 Pages) Ohmite Mfg. Co. – PulsEater Ceramic Composition Available in E12 Ohmic values
The “A” Series non-inductive,
ceramic composite resistors
are designed for a variety
of applications where high
energy handling capabilities
are crucial. These resistors are
ideal for any application which
is subject to surges, high peak
power, or impulse energy.
Their unique design allows
uniform distribution of energy
throughout their structure
which results in low thermal
stress. The high-temperature,
solvent-resistant epoxy coating
carries a UL94V0 flammabil-
ity rating which is suitable for
almost any environment.
FEATURES
• High Surge Energy
• Non-Inductive
• Small Size
APPLICATIONS
• Motor Drives
• Power Supplies, UPS
• Power Conversion
• In-Rush Current Limiting
