Enhancing Electronic Detonation Systems with Vishay’s TANTAMOUNT Solid Tantalum Chip Capacitors: A Robust Design 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 and undergo rigorous testing to guarantee dependable detonation in tough conditions, with a low 0.005CV DCL.

Vishay Intertechnology, Inc. has launched a new line of TANTAMOUNT surface-mount solid tantalum molded chip capacitors that are tailored for use in electronic detonation systems. The Vishay Sprague TX3 series capacitors have a strong mechanical design, low leakage current, and undergo rigorous testing to ensure improved performance and reliability compared to standard tantalum capacitors and MLCCs.

The capacitors launched today have low DCL values of 0.005CV and a high energy density compared to other types of capacitors. This allows them to provide 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 superior dielectric formation ensures consistent electrical performance even in tough conditions.

In order to guarantee reliability, TX3 series capacitors undergo more rigorous testing compared to standard commercial options. Each capacitor is tested for surge current using standard methods, and also undergoes two additional screenings to ensure consistent electrical characteristics across production lots. The capacitive element and lead frame of the devices are protected by a durable hard plastic resin, providing a strong solution. These capacitors have higher shock (100 g) and vibration (20 g) resistance compared to MLCCs, meeting MIL-STD-202 standards.

The TX3 series is available in two case sizes, B (EIA 3528-21) and C (EIA 6032-28), with capacitance ranging from 10 µF to 100 µF and voltage ratings between 16 V and 25 V. The devices have a capacitance tolerance as low as ±10% and ESR values ranging from 0.700 Ω to 2.3 Ω at +25 °C. They can handle ripple currents up to 0.438 A and operate at high temperatures up to +125 °C. The TX3 series features lead (Pb)-free terminations, is RoHS-compliant, halogen-free, and is considered Vishay Green.

The new solid tantalum capacitors are currently in stock for sampling and production in small quantities. It will take approximately 10 to 12 weeks to fulfill orders. Contact a Vishay representative in your area for pricing information.
