Enhancing Electronic Detonation Systems Performance with Vishay’s TANTAMOUNT Solid Tantalum Chip Capacitors

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

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 are built with a sturdy design, low leakage current, and rigorous testing standards to provide improved performance and reliability compared to commercial tantalum capacitors and MLCCs.

The capacitors released today have low DCL values of 0.005CV and a high energy density of tantalum, making them capable of delivering more energy for effective ignition. This makes them perfect for remote detonation systems that require reliable discharge in mining and demolition settings. The use of tantalum anode technology and Vishay's high-quality dielectric formation ensures consistent electrical performance in challenging environments.

For increased reliability, TX3 series capacitors undergo more rigorous testing compared to standard commercial capacitors. They are subjected to 100% surge current testing using standard methods, as well as two additional screenings to ensure consistent electrical characteristics across different production batches. The capacitors are protected by a hard plastic resin that encapsulates both the capacitive element and lead frame, providing a sturdy solution. In comparison to MLCCs, TX3 capacitors have higher shock (100 g) and vibration (20 g) resistance as per MIL-STD-202 standards.

The TX3 series comes in two case sizes, B and C, with capacitance ranging from 10 µF to 100 µF and voltage ratings from 16 V to 25 V. The capacitance tolerance can go down to ± 10%. These devices have ESR ranging from 0.700 Ω to 2.3 Ω at +25 °C, ripple current up to 0.438 A, and can operate at high temperatures up to +125 °C. They have lead-free terminations, are RoHS-compliant, halogen-free, and certified as Vishay Green.

You can now get samples and bulk quantities of the recently released solid tantalum capacitors, but you may have to wait 10 to 12 weeks for delivery. For pricing information, reach out to a Vishay representative in your area.
