Enhancing Electronic Detonation Systems with Vishay’s TANTAMOUNT Solid Tantalum Chip Capacitors: A Robust Solution for Harsh Environments
Vishay's solid tantalum chip capacitors improve the performance of electronic detonation systems. TANTAMOUNT devices have a strong design and low 0.005CV DCL, along with strict testing standards 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. These capacitors, known as the Vishay Sprague TX3 series, are built with a strong mechanical design and have low leakage current (DCL) and strict testing standards to ensure improved performance and reliability compared to standard tantalum capacitors and MLCCs.
The capacitors released today have low DCL values of 0.005CV and a high energy density of tantalum, making them able to deliver more energy for proper ignition. This makes them well-suited for remote detonation systems in mining and demolition applications that require reliable discharge. The use of tantalum anode technology and Vishay's high-quality dielectric formation ensures consistent electrical performance in harsh environments.
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 extra screenings to ensure consistent electrical characteristics across different production lots. These capacitors have a durable design, with their capacitive element and lead frame enclosed in hard plastic resin. They have higher resistance to shock (100 g) and vibration (20 g) compared to MLCCs, meeting MIL-STD-202 standards.
The TX3 series comes in two case sizes, B and C, with a capacitance range of 10 µF to 100 µF and voltage ratings from 16 V to 25 V. The capacitance tolerance can be as low as ±10%. These devices have ESR values ranging from 0.700 Ω to 2.3 Ω at +25 °C, with a ripple current up to 0.438 A and can operate at temperatures up to +125 °C. They have lead (Pb)-free terminations and are compliant with RoHS, halogen-free, and are Vishay Green certified.
The new solid tantalum capacitors are currently available for sampling and production in both small and large quantities. Lead times for orders are estimated to be between 10 to 12 weeks. For information on pricing, it is recommended to reach out to a Vishay representative in your
