Enhancing Electronic Detonation Systems with Vishay’s TANTAMOUNT Solid Tantalum Chip Capacitors: A Robust Solution for Reliable Performance in Harsh Environments

Vishay's solid tantalum chip capacitors improve the performance of electronic detonation systems. TANTAMOUNT devices have a strong design, low 0.005CV DCL, and strict testing criteria to guarantee dependable detonation in tough conditions.

Vishay Intertechnology, Inc. has released a new line of TANTAMOUNT surface-mount solid tantalum molded chip capacitors that are made for electronic detonation systems. The Vishay Sprague TX3 series capacitors have a durable design, low leakage current, and strict testing standards, offering better performance and reliability compared to regular tantalum capacitors and MLCCs.

The capacitors released today have a low DCL value of 0.005CV and a high energy density compared to other types of capacitors. This allows them to deliver more energy for reliable ignition, making them well-suited for remote detonation systems in mining and demolition. The use of tantalum anode technology and Vishay's high-quality dielectric formation ensures stable electrical performance even in tough environments.

In order to guarantee reliability, TX3 series capacitors undergo more rigorous testing compared to standard commercial capacitors. Each capacitor is tested for surge current using standard methods and undergoes two additional screenings to ensure consistent electrical characteristics across different production batches. The capacitors are encased in hard plastic resin to provide durability, and they offer higher shock (100 g) and vibration (20 g) resistance compared to MLCCs, meeting MIL-STD-202 standards.

The TX3 series is available in two different case sizes: B (EIA 3528-21) and C (EIA 6032-28). These capacitors have a capacitance range of 10 µF to 100 µF and voltage ratings from 16 V to 25 V. The capacitance tolerance can go as low as ± 10%. The ESR ranges from 0.700 Ω to 2.3 Ω at +25 °C, with a ripple current up to 0.438 A, and can operate at high temperatures up to +125 °C. These devices have lead (Pb)-free terminations, are RoHS-compliant, halogen-free, and are part of the Vishay Green initiative.

If you are looking to purchase the new solid tantalum capacitors, you can request samples and production quantities now. The lead times for these capacitors are currently 10 to 12 weeks. For information on pricing, please reach out to your nearest Vishay representative.
