On February 13, 2014, Littelfuse , a global leader in circuit protection, announced the introduction of its new dual-channel, general-purpose TVS diode array (SPA ? Diode) family that protects sensitive devices from electrostatic discharge ( ESD ), Electrical Fast Transient (EFT) and lightning induced surges are optimized for damage. The SM Series of TVS Diode Arrays offer five voltage options: 5V, 12V, 15V, 24V, 36V. All voltage options have very low dynamic resistance, which provides clamping performance superior to similar components. This ensures optimal performance and thus protects modern sensitive electronic devices. The SM Series of TVS Diodes can absorb the highest levels of repetitive ESD strikes in the international standard without compromising performance and safely dissipate up to 24A of inductive surge current. The product provides strong protection against electrical threats for data communication ports such as RS 232, RS-485, RS-422, and RS-423. These ports are commonly used in automation equipment, diagnostic equipment, safety and alarm systems, printers, and test equipment. and many more.
Chad Marak, Director of Product Lines for TVS Diode Arrays, said: " Littelfuse 's SM Series of TVS Diode Arrays offer two to three times better ESD tolerance than competing solutions to ensure the highest reliability of outdoor electronics." Littelfuse 's products have an extremely low dynamic resistance and produce the lowest clamping voltage in the industry, making them an ideal solution for protecting sensitive electronic equipment.
Features
? Greatly reduced clamping voltage to ensure modern integrated circuits are protected from electrical threats such as industry-defined ESD and lightning-induced surges
• Provides 25% more power handling than competing solutions, providing a higher electrical threat design margin than industry standards.
Availability
The SM series is available in a SOT23-3 package of 3,000 per roll. Samples are available; samples are available from authorized Littelfuse distributors worldwide.
The micro Vibration Motor is introduced:
Micro vibration motor is mainly used for adult health care products and toys, micro vibration motor is a Dc Motor, the motor shaft with an eccentric wheel, the use of most of the micro vibration motor voltage is lower than 6 v, probably between 6 mm to 15 mm in diameter, when the motor rotation, eccentric circle particles is not the core of the motor, the motor often lose their balance, due to the inertia effect.
Characteristics: small volume, strong vibration;
Features: small size, fast speed, stable performance, low price, can use battery drive,Can change the different materials of the pendulum head
Method of use: the best stable in horizontal plane, installed on the dc Micro vibration motor output shaft parts, cannot use a hammer to knock, knock prone to press into the Micro vibration motor drive, may cause damage to internal components, and cannot be used in the case of blocked.
Operating temperature range:
Mini Vibration Motor should be used at a temperature of -10~60℃.
The figures stated in the catalog specifications are based on use at ordinary room temperature catalog specifications re based on use at ordinary room temperature (approximately20~25℃.
If a Mini Vibration Motor is used outside the prescribed temperature range,the grease on the gearhead area will become unable to function normally and the motor will become unable to start.Depending on the temperature conditions ,it may be possible to deal with them by changing the grease of the motor's parts.Please feel free to consult with us about this.
Storage temperature range:
Mini Vibration Motor should be stored ta a temperature of -15~65℃.
In case of storage outside this range,the grease on the gearhead area will become unable to function normally and the motor will become unable to start.
Service life:
The longevity of Mini Vibration Motor is greatly affected by the load conditions , the mode of operation,the environment of use ,etc.Therefore,it is necessary to check the conditions under which the product will actually be used .The following conditions will have a negative effect on longevity.Please consult with us should any of them apply.
â—Use with a load that exceeds the rated torque
â—Frequent starting
â—Momentary reversals of turning direction
â—Impact loads
â—Long-term continuous operation
â—Forced turning using the output shaft
â—Use in which the permitted overhang load or the permitted thrust load is exceeded
â—A pulse drive ,e.g.,a short break,counter electromotive force,PWM control
â—Use of a voltage that is nonstandard as regards the rated voltage
â—Use outside the prescribed temperature or relative-humidity range,or in a special environment.
â—Please consult with us about these or any other conditions of use that may apply,so that we can be sure that you select the most appropriate model.
when it come to volume production,we're a major player as well .each month,we rurn out 600000 units,all of which are compliant with the rohs directive.Have any questions or special needed, please contact us, we have the engineer group and best sales department to service to you Looking forward to your inquiry. Welcome to our factory.
