216-259 uF Motor Start Capacitor 110-125V AC - Durable Replacement

In this review of the 216-259 uF motor start capacitor the bottom line is simple: this is a reliable, purpose-built replacement for single phase motors that need a compact, UL rated start capacitor. The reviewer found it best suited to HVAC compressors, pumps and household appliances where a high-capacitance, oil-filled start unit is required. Its rugged phenolic resin case, PCB-free construction and UL rating make it a practical repair part for technicians and DIYers who need a straightforward OEM-style replacement.

Key Features

• High capacitance: 216-259 uF delivers the strong starting boost required for single phase motors and compressors, helping motors reach operating speed reliably.
• Broad voltage compatibility: Rated for 110-125 VAC and 50/60 Hz, it fits common household and light industrial AC motor circuits without voltage mismatch concerns.
• Durable construction: The electrolytic oil filled design in a rugged phenolic resin case provides mechanical protection and stable performance under normal duty.
• Wide temperature range: Operates from -40 C to +65 C (-40 F to +149 F), useful for HVAC and garage environments where temperatures can vary widely.
• Convenient terminals: 1/4 in quick disconnect terminals make installation fast and compatible with standard motor wiring connectors.
• UL listed and PCB-free: UL E492933 rating and PCB-free construction provide peace of mind for safety and environmental concerns.

Who It's For

The capacitor is aimed at service technicians, maintenance teams and handy homeowners replacing OEM start capacitors in HVAC units, compressors, washing machines and pumps. It is particularly appropriate when a compact round can (1.44 in diameter, 2.75 in height) is required to match existing mounting footprints.

Those who need extreme miniaturization or surface-mount electronics should look elsewhere, as this is a through-panel, round electrolytic start capacitor intended for motor replacement, not low-profile board-mounted applications.

Pros & Cons

Pros

• Works well as an OEM replacement and fits common motor applications, matching expected form and function.
• Good value: customers report solid performance and reasonable price for a 5 year warranted, UL rated unit.
• Easy installation thanks to 1/4 in quick disconnect terminals and a common round can size.
• PCB-free and oil filled construction offers durability and safety advantages over unknown alternatives.

Cons

• Size receives mixed feedback; the compact can may be smaller than some expect, so check dimensions before purchase.
• Designed specifically for start duty; it is not a general-purpose or run capacitor for continuous motor operation.
