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 are designed to improve the performance of electronic detonation systems. The TANTAMOUNT devices have a strong design, low 0.005CV DCL, and undergo rigorous testing to ensure reliable detonation even in harsh environments.
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, have a strong mechanical design and meet strict testing standards to provide 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 due to their tantalum material, making them efficient for providing the necessary energy for ignition. These capacitors are well-suited for remote detonation systems in mining and demolition settings where reliable discharge is crucial. The combination of tantalum anode technology and Vishay's superior dielectric formation ensures consistent electrical performance even in harsh conditions.
In order to guarantee reliability, TX3 series capacitors undergo more rigorous testing than typical commercial capacitors. Each capacitor is tested with 100% surge current using standard screening methods, and also goes through two extra screenings to ensure consistent electrical characteristics across different production lots. The capacitors are protected by a tough plastic resin that encapsulates the capacitive element and lead frame, making them durable. 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 different 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 be as low as ± 10%. These devices have ESR values ranging from 0.700 Ω to 2.3 Ω at +25 °C, a ripple current of up to 0.438 A, and can operate at high temperatures up to +125 °C. They have lead (Pb)-free terminations, are RoHS-compliant, halogen-free, and part of the Vishay Green initiative.
You can now obtain samples and larger quantities of the recently released solid tantalum capacitors, but there may be a lead time of 10 to 12 weeks. Contact your nearby Vishay representative for pricing information.
