Sprague Capacitors in a WaveTek 2001 Sweep Generator
« on: August 29, 2021, 07:00:54 AM »

Hello all.  I'm replacing some faulty Sprague 100 uF 25V electrolytic capacitors  on my WaveTek 2001 sweep generator and was wondering what the wide red stripe is on the anode? Does it indicate the polarity or could it be leakage?  I will post a picture of these caps ASAP.

Old caps worth 35 cents each are not worth it. Buy new at 35 cents each from Mouser.

A 100uf cap is probably electrolytic, so yes, the stripe is polarity.

Vishay acquired many of the Sprague Capacitor products.

REPLACING Electrolytic Capacitors
Choose Quality Manufacturer from Known Electronics Distributor
FAKE and POOR Quality found from Eastern Asian sellers

MANUFACTURER:  Cornell Dubliner Electronics (CDE), Panasonic, Vishay
DISTRIBUTOR: Digi-Key, Mouser

For Radial Electrolytic Capacitors, Compare:
SIZE (Diameter, Height)
LEAD SPACING (mm) for Best Fit (2.5, 3.5, 5.0mm)
VOLTAGE (VDC) you substitute to next Voltage rating (35 VDC)
