No. P-KVA-002 DATE 2008-10 PRODUCTS DATA SHEET ESD protection SURGE ABSORBER Type KVA LEAD FREE Size 1005, 1608 OUTLINE The signal transmission rate of personal computer peripheral devices and digital devices as represented by USB2.0 devices is being increased year by year, and countermeasures against ESD are critical in high-frequency bands. We have developed Type KVA Surge Absorber to protect the circuits of various electronic devices sensitive to ESD. Since the surge absorber has a low capacitance of 0.08 pF, it is applicable to high-speed signal lines. The ecology design of Type KVA is environmentally friendly because of Lead-free and Halogen-free. APPLICATION The product is suitable for elimination of ESD on high-speed signal lines that may be affected by signal waveform deformation. (USB2.0, IEEE1394, HDMI interfaces, SCSI ports, etc.) FEATURES 1. Usable on high-speed signal lines 2. Low capacitance (size 1005 : 0.06pF typ.) 3. Large ESD endurance and high insulation resistance 4. No polarity. Protection of circuit against ESD from both directions 5. Ultra-small size : 1005 (1.0 x 0.5 x 0.35 mm), 1608 (1.6 x 0.8 x 0.45 mm) 6. Suitable for automatic mounting by chip placer 7. Precise dimensions allows high-density mounting and symmetrical construction of terminal provide "Self-Alignment". 8. Resistance to soldering heat : Reflow or flow soldering 10 seconds at 260C 9. High accuracy carrier tape by using pressed pocket ensures excellent mounting. 10. Lead-free and RoHS Compliant RATING Item Ratings -40 ~ +125C 24 VDC 1000 V max. (650 V typ.) 200 V max.

Application Notes for Surge Absorber 1. Circuit Design 5. Environmental Conditions Type KVA Surge Absorber is a part for protection from static electricity and cannot be used for protection from lightning surge. Before using Type KVA Surge Absorber, sufficiently examine its electrical characteristics and the circuit conditions to be mounted. (1) Type KVA should always be operated below the rated voltage. (2) Use Type KVA under the condition of category temperature. (1) Type KVA should not be operated in acid, alkali, or active gas atmosphere. (2) Type KVA should not be vibrated, shocked, or pressed excessively. (3) Type KVA should not be operated in a flammable or explosive atmosphere. (4) After mounting Type KVA on a board, covering Fuses with resin may affect to the electric characteristics of Type KVA. Please be sure to evaluate it in advance. Type KVA should be selected by determining the operating conditions that will occur after final assembly, or estimating potential abnormalities through cycle testing. 2. Assembly and Mounting During the entire assembly process, observe Type KVA body temperature and the heating time specified in the performance table. In addition, observe the following items : (1) Mounting and adjusting with soldering irons are not recommendable since temperature and time control is difficult. In case of emergency for using soldering irons, be sure to observe the conditions specified in the performance table. (2) Type KVA body should not have direct contact with a soldering iron. (3) Once Type KVA mounted on the board, they should never be remounted on boards or substrates. (4) During mounting, be careful not to apply any excessive mechanical stresses to Type KVA. 6. Emergency In case of fire, smoking, or offensive odor during operation, please cut off the power in the circuit or pull the plug out. 7. Storage (1) Type KVA should be stored at room temperature (-10C ~ +40C) without direct sunlight. Direct sunlight may cause decolorization and deformation of the exterior and taping. Also, there is a fear that solderability will be remarkably lower in high humidity. (2) If the products are stored for an extended period of time, please contact Matsuo Sales Department for recommendation. The longer storage term causes packages and tapings to worsen. If the products are stored for longer term, please contact Matsuo Sales Department for advice. (3) The products in taping, package, or box should not be given any kind of physical pressure. Deformation of taping or package may affect automatic mounting. 8. Disposal 3. Solvents For cleaning of Type KVA, immersion in isopropyl alcohol for 90 seconds (at 20 ~ 30C liquid temp.) will not be damaged. If organic solvents (Pine AlphaTM, Techno CareTM, Clean ThroughTM, etc.) will be applied to Type KVA, be sure to preliminarily check that the solvent will not damage the Type KVA. 4. Caution During Usage When Type KVA are disposed of as waste or "scrap", they should be treated as "industrial waste". Type KVA contain various kinds of metals and resins. 9. Samples Type KVA received as samples should not be used in any products or devices in the market. Samples are provided for a particular purpose such as configuration, confirmation of electrical characteristics, etc. Type KVA should never be touched in use.
