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 with low 0.005CV DCL and strict testing requirements 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 strong design, low leakage current, and undergo rigorous testing to ensure improved performance and reliability compared to regular tantalum capacitors and MLCCs.
The capacitors released today have low DCL values of 0.005CV and a high energy density compared to other types of capacitors, particularly due to the use of tantalum. This allows them to provide more energy for reliable ignition, making them well-suited for remote detonation systems in mining and demolition. The tantalum anode technology and high-quality dielectric formation from Vishay ensure consistent electrical performance in challenging conditions.
In order to guarantee dependability, TX3 series capacitors undergo more rigorous testing compared to regular commercial capacitors. Each component is tested for surge current using standard methods, and also undergoes two more tests to ensure consistent electrical characteristics across different batches. The capacitors are protected by a sturdy resin encapsulation around the capacitive element and lead frame, providing a durable 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 a capacitance range of 10 µF to 100 µF and voltage ratings between 16 V to 25 V. The devices have a capacitance tolerance of ± 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 and is RoHS-compliant, halogen-free, and Vishay Green certified.
If you are interested in the new solid tantalum capacitors, you can request samples or order production quantities. Lead times for delivery are currently estimated to be between 10 to 12 weeks. For pricing information, please reach out to a Vishay representative in your area.
