Product Description

The Keltron 35V 1000uF Electrolytic Capacitor is a premium-grade polarized electronic component designed for high-capacity energy storage and effective noise filtration. Manufactured by Keltron, a leader in high-reliability passive components, this capacitor features a slim 10x25mm profile, making it suitable for compact power supply units, motor drivers, and audio amplification circuits. With a 35V rating and a 105°C temperature tolerance, it offers exceptional stability and a long operational life in both consumer electronics and industrial power applications where ripple current management is essential.

Key Features

Genuine Keltron Quality: Sourced from a trusted manufacturer known for strict adherence to capacitance and ESR standards.
High Capacitance Density: Provides 1000uF of storage in a compact 10x25mm frame, ideal for smoothing DC output.
105°C Industrial Rating: Designed to operate reliably in high-heat environments, significantly outlasting standard 85°C variants.
Low ESR Performance: Minimizes internal heating and voltage drops, making it efficient for switching power supplies.
Standard Radial Leads: Features a 5mm lead pitch for easy integration into standard through-hole PCB layouts.
Rugged Aluminum Casing: Includes a safety vent on the top to protect the circuit in the event of extreme electrical stress.

Technical Details

Dielectric: Aluminum Oxide.
Mounting: Through-Hole (Radial).
Lead Material: Tinned copper-clad steel for high solderability.

Prototyping and Engineering Tips from Robogears

Polarity Verification: CRITICAL: This capacitor is polarized. The Negative (-) lead is the shorter one and is marked by the wide light-colored stripe on the Keltron branding. Reversing the polarity in a 35V circuit will cause the component to heat up rapidly and potentially burst.
Voltage Safety Margin: For industrial reliability, it is recommended to run this capacitor at no more than 80% of its rated voltage (approx. 28V). This unit is the perfect choice for 24V DC systems, providing a safe buffer against voltage spikes.
Smoothing Calculations: If you are building a full-wave bridge rectifier, a 1000uF capacitor is a standard "rule of thumb" starting point for every 1 Ampere of load current to maintain low ripple voltage.
Mechanical Clearance: Given the 25mm height, ensure your enclosure has enough vertical clearance. If space is tight, avoid bending the leads at the base of the capacitor; instead, use a small "spacer" or leave 1-2mm of lead above the PCB to prevent mechanical stress on the rubber seal.
Soldering Best Practices: Use a clean soldering iron tip and apply heat for no longer than 3 seconds. Excessive heat transfer through the leads can dry out the electrolyte near the seal, leading to premature aging of the component.

Package Includes

1 x Keltron 35V 1000uF Electrolytic Capacitor

Disclaimer: Product images are shown for illustrative purposes only. While we prioritize Keltron brand stock, the external sleeve color or text layout may vary between manufacturing batches. All technical specifications and 1000uF/35V performance standards remain as described.

Safety Warning: Ensure the capacitor is fully discharged before handling, especially when used in power supply stages. Never exceed the 35V DC limit. If the top of the aluminum can appears "swollen" or "domed," the capacitor has failed and must be replaced immediately to prevent circuit damage.
