85 ºC, Industrial Grade
Type WBR capacitors are the preferred choice for
many varied industrial applications because they have
high capacitance and extended life characteristics. The
rugged construction delivers the high vibration resis-
tance required in industrial applications
Highlights
• High capacitance
• Extended life
• Rugged construction
• High vibration resistance
