1000uF 50V Radial Electrolytic Capacitor

Technical Details

• Dielectric: Aluminum Electrolytic.

• Casing: Aluminum cylindrical can with an insulated PVC sleeve.

• Shelf Life: High reliability with minimal leakage current over time.

Prototyping and Engineering Tips from Robogears

• Polarity Verification: CRITICAL: This is a polarized capacitor. The shorter lead and the stripe on the body indicate the Negative (-) terminal, while the longer lead is Positive (+). Connecting this capacitor in reverse can lead to immediate failure, leakage, or physical rupture.

• The 80% Voltage Rule: For maximum longevity, never operate a capacitor at its maximum rated voltage. For this 50V unit, it is best practice to use it in circuits with a maximum steady-state voltage of 40V.

• Power Supply Filtering: This 1000µF value is the "Gold Standard" for smoothing out the output of a bridge rectifier. A general rule of thumb is to use 1000µF to 2000µF per Ampere of output current to achieve low ripple voltage.

• ESR and Parallel Pairing: In high-frequency switching power supplies, you can improve performance by placing a small 0.1µF ceramic capacitor in parallel with this 1000µF electrolytic. The electrolytic handles the bulk energy, while the ceramic filters out high-frequency noise that the larger capacitor's internal resistance might miss.

• Mechanical Stability: Because 1000µF capacitors are relatively heavy, ensure they are seated flush against the PCB. In high-vibration applications (like RC vehicles or industrial machinery), consider adding a dab of electronics-grade silicone adhesive to prevent the leads from snapping due to fatigue.

Disclaimer: Product images are shown for illustrative purposes only. The exact physical dimensions (height/diameter) or the color of the PVC sleeve may vary slightly between manufacturing batches, but all technical specifications and Keltron performance standards remain as described.

Safety Warning: Electrolytic capacitors can store a significant electrical charge even after power is disconnected. Always discharge the capacitor safely using a resistor before handling or soldering. Never exceed the 50V rating, and ensure the operating environment does not exceed the 105°C limit to prevent premature drying of the internal electrolyte.
