厚膜电阻主要是指采用印刷而成的电阻。这种电阻有长方形，带型，曲线形或者是其他的形状。常用在精密电阻，功率电阻的制造中。
　　常用的厚膜电阻采用金属钌（liao二声）系电阻浆料印刷烧结而成。电阻浆料包含氧化钌，有机溶剂和玻璃珠，烧结后的电阻由两方面组成：氧化钌本身的电阻和电阻

New Vishay Thick Film Power Resistors in TO220 and TO247 Packages Feature Resistance Range of 0.010 Ohms to 1 Megohm, Inductance
of Less than 0.1 Microhenries
30-W, 50-W and 100-W Vishay Sfernice resistors use direct-mounting ceramic package design

This release in:
MALVERN, PENNSYLVANIA — June 24, 2005 — Vishay Intertechnology, Inc. (NYSE: VSH) has extended its family of thick film power
resistors with the introduction of 30-W, 50-W and 100-W devices in industry-standard TO220 and TO247 packages. The resistors
use a ceramic package design (with no metal tab) for direct-mounting on heatsinks, and feature an exceptionally low inductance
of less than 0.1 μH, suiting them for use in power conversion and control applications in a wide variety of industries.
The new Vishay Sfernice devices are available in a wide range of resistance values, from 0.010 Ω to 550 kΩ for the
families, and from 0.015 Ω to 1 MΩ for the . All of the devices have a temperature coefficient of 150 ppm/ °C for values above 0.5 Ω. Their compact, low-profile, direct-mounting
package design improves heat dissipation and reduces space on printed circuit boards.
The LTO resistors are designed for use in pulse-loading applications, as snubber or bleeder resistors, and in a variety of
other high-power equipment such as uninterruptible power supplies (UPS), power conversion for traction and industrial drives,
and in medical, automotive, and industrial control environments. The resistors use an optimized process of printed thick film
technology on an alumina substrate to achieve tolerances as low as ± 1 %, and up to ± 10 %.
All of the resistors are compatible with tin/lead (Sn/Pb) and lead (Pb)-free soldering processes, allowing use by all assemblers
transitioning to lead (Pb)-free processes to meet incoming legislation and voluntary environmental manufacturing codes. In
addition, all devices comply with EU directives on vehicle end of life, including 2000/53/EC End of Vehicle Life Directive
(ELV) and 2000/53/EC Annex II to End of Vehicle Life Directive (ELV II). All devices also meet 2002/95/EC Restriction of the
use of Hazardous Substances Directive (RoHS) and 2002/96/EC Waste Electrical and Electronic Equipment Directive (WEEE).
Samples and production quantities of the new Vishay Sfernice LTO resistors are available now, with a lead time of eight weeks
for larger orders.
Vishay Intertechnology, Inc., a Fortune 1000 Company listed on the NYSE (VSH), is one of the world's largest manufacturers
of discrete semiconductors (diodes, MOSFETs, and infrared optoelectronics) and passive electronic components (resistors, inductors,
and capacitors). These components are used in virtually all types of electronic devices and equipment, in the industrial,
computing, automotive, consumer, telecommunications, military, aerospace, power supplies, and medical markets. Vishay’s product
innovations, successful acquisition strategy, and "one-stop shop" service have made it a global industry leader. Vishay can
