Additional Details:

The "SFS37" likely refers to a specific series within CDE's aluminum electrolytic capacitor range. The "S" likely indicates snap-in terminals. "55K" may be related to voltage rating and capacitance (refer to the datasheet for accurate values). The "375B" will be a manufacturing or date code, the "-F" is a terminal style indicator. These capacitors are constructed with an aluminum foil electrode and a liquid electrolyte. Their performance characteristics are affected by temperature and frequency. The operating temperature range is typically -40°C to +85°C or higher, depending on the specific series. Refer to the CDE datasheet for the exact capacitance, voltage rating, ripple current rating, ESR, and impedance at various frequencies and temperatures. The datasheet also specifies the recommended mounting guidelines and storage conditions. The expected lifetime is dependent on operating temperature, ripple current, and applied voltage. The case size and terminal configuration are also specified in the datasheet.
