Enhancing Electronic Detonation Systems with Vishay’s TANTAMOUNT Solid Tantalum Chip Capacitors: Robust Design and Stringent Testing 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 low 0.005CV DCL, along with strict testing standards to ensure dependable detonation in challenging conditions.

Vishay Intertechnology, Inc. has released a new line of TANTAMOUNT surface-mount solid tantalum molded chip capacitors made for electronic detonation systems. These Vishay Sprague TX3 series capacitors are built with a strong mechanical design, low leakage current (DCL), and strict testing standards, providing better performance and reliability compared to commercial tantalum capacitors and MLCCs.

The capacitors being introduced 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 suitable for use in remote detonation systems in mining and demolition. The use of tantalum anode technology and Vishay's high-quality dielectric formation ensures that these capacitors maintain stable performance even in harsh conditions.

In order to guarantee reliability, TX3 series capacitors undergo more rigorous testing than regular commercial capacitors. Each capacitor is tested for surge current using standard methods, and also undergoes two additional screenings to ensure consistent electrical performance across different production lots. The capacitors are protected by a hard plastic resin casing, providing a durable solution. Compared to MLCCs, TX3 capacitors have higher shock (100 g) and vibration (20 g) resistance according to MIL-STD-202 standards.

The TX3 series capacitors are available in two different case sizes, B and C, with capacitance ranging from 10 µF to 100 µF and voltage ratings between 16 V and 25 V. The capacitance tolerance of these devices can go down to ±10%. They have an ESR range of 0.700 Ω to 2.3 Ω at a temperature of +25 °C, with a ripple current up to 0.438 A and can operate at high temperatures up to +125 °C. The TX3 series capacitors have lead-free terminations, are RoHS-compliant, halogen-free, and part of the Vishay Green initiative.

You can now request samples and order production quantities of the recently released solid tantalum capacitors, with a waiting time of 10 to 12 weeks. Contact your Vishay representative for pricing information.
