Coupling, by-passing high frequency circuits also use HV ceramic disc capacitors. • These applications require: - a high internal resistance. - a high dielectric strength. - low or moderate losses at working frequencies (from 50 Hz up to 10 kHz). The active power (or losses) being: Wa = 2ΠFC tg δ V2 = k (Ctg δ) (FV2) This shows that improved performances are obtained when: - Good dielectric properties (low tg δ) and - No long term overvoltage are present and - Capacitors free of “partial discharge” (corona) effect, up to rated rms voltage. TPC is able to perform “discharge free test” and may guarantee a rate as low as 5 picocoulombs at Vrms upon request. • High voltage capacitors for AC uses are mainly made of type II dielectrics. Most of these materials except strontium titanate exhibit a significant non-linearity. Consequently, the capacitance value depends on the voltage across the component and on the frequency of the applied signal. • Laser pulses circuitry, high energy/high voltage test equipment (HV accelerators, physics research) require products especially adapted to their specific requirements. • Because of the high energy involved, the design of the capacitors have to provide: - a very low ESR (equivalent series resistance) to minimize the lossed energy. W= ∫ ip (ESR 2) di - a very low ESL (equivalent series inductance) to keep the correct pulse shape. Typically due to the design of the electrodes, the products exhibit: - ESR: ~ 10 mΩ - ESL: < 30 nH - peak current up to 50 kA dV or short signal rise - a high withstanding of very large dt time. - a high energy density J 1 J = 2 k εo εr E2 (with E = V/m) even under high electric field, (implying that εr is very little voltage dependent). Through the use of almost linear or non-voltage dependent capacitors, the stored energy can reach 50 to 100 J/liter for the HP/HW products. • To ensure these properties, traditional ferroelectric type II capacitors cannot be used due to their electrostrictive and piezoelectric properties. The capacitors use quasi “paraelectric”, strontium-based, ceramic material. • The main applications are coupling, decoupling, multipliers circuits, HV DC power supplies, high voltage dividers. 1 High Voltage Ceramic Capacitors Type HP/HW – Strontium-based Dielectric FEATURES • • • • • Excellent behavior on pulse and fast discharge conditions Excellent capacitance vs voltage characteristic Low dissipation factor Very low Corona effect Coated and uncoated devices available APPLICATIONS • • • • • • High-voltage supply for gas lasers High-voltage divider Marx generators Power generators High-voltage power supply High-voltage coupling device TECHNOLOGY • • • • HP range: Coated capacitor HW range: Uncoated capacitor Connections: M5 Marking: on each part: logo – type – capacitance – rated voltage • Delivery mode: bulk in carton box • Dielectric Type II: N4700 class (see typical curves page 8) • Power line coupling system for Internet & Telecom DIELECTRIC CHARACTERISTICS TPC code Dielectric class (DIN) Operating temperature range (ºC) Capacitance change with temperature (%) Typical dielectric constant Dielectric strength kVDC/mm Dissipation factor (1kHz/1VRMS/20ºC) Insulation resistance (1000VD/20ºC/60s) ELECTRICAL CHARACTERISTICS E N4700 -30/+85 +22/-33 1850 8.0 <20.10-4 >100GΩ Rated voltage (VR) Test voltage (VE) (50Hz, in oil, 60s) Temperature ranges Storage Operating Temperature characteristic Dissipation factor (20ºC, 1kHz, 1VRMS) Insulation resistance (1000Vdc/60s) Capacitance range (20ºC – 1kHz – 1VRMS) Tolerance Self-inductance *up to 150kVdc: upon request 2 15 to 50 kVdc* 12 to 48 kVac -40 +125ºC -30 +85ºC N4700 <20.10-4 >100GΩ 390pF to 5600pF Standard: ±20% On request: ±10% L ≤ 30nH High Voltage Ceramic Capacitors Type HP/HW – Strontium-based Dielectric HP RANGE: COATED DEVICES REFERENCES – VOLTAGE AND CAPACITANCE RANGE ø d H All fixtures: M5 (0.197) L M Part Number HP30EX0561M - HP30EX0751M - HP30EX0102M - HP40EX0152M - HP40EX0182M - HP40EX0202M - HP50EX0252M - HP50EX0272M - HP50EX0332M - HP60EX0372M - HP60EX0402M - HP60EX0502M - HP60EX0562M - HP30EY0501M - HP30EY0561M - HP30EY0751M - HP40EY0102M - HP40EY0132M - HP40EY0152M - HP50EY0202M - HP50EY0222M - HP50EY0252M - HP60EY0302M - HP60EY0332M - HP60EY0372M - HP60EY0402M - HP30E30561M - HP40E30821M - HP40E30102M - HP40E31121M - HP50E30152M - HP50E30172M - HP50E30202M - HP60E30272M - HP60E30302M - HP60E30332M - HP30E40391M - HP40E40751M - HP50E40102M - HP50E40142M - HP60E40172M - HP60E40202M - HP60E40242M - HP40E50561M - HP50E50102M - HP60E51651M - HP50E90501M - HP60396750M - HP60E90751M - HP60398250M - - Rated Voltage kVdc 15 Rated Votage kVac 10 Test Voltage kVac 12 20 15 18 30 20 24 40 30 36 50 40 48 100 70 80 Corona Capacitance Inception ±20% Voltage (pF) (kVac) (pC) 560 750 1000 1500 1800 2000 10 2500 2700 3300 3700 4000 5000 5600 500 560 750 1000 1300 1500 10 2000 2200 2500 3000 3300 3700 4000 560 820 1000 1120 15 1500 1700 2000 2700 3000 3300 390 750 1000 20 1400 1700 2000 2400 560 25 1000 1650 500 675 44 750 825 Dimensions millimeters (inches) ر1 28 28 28 38 38 38 48 48 48 58 58 58 58 28 28 28 38 38 38 48 48 48 58 58 58 58 28 38 38 38 48 48 48 58 58 58 28 38 48 48 58 58 58 38 48 58 48 58 58 58 (1.100) (1.100) (1.100) (1.500) (1.500) (1.500) (1.900) (1.900) (1.900) (2.283) (2.283) (2.283) (2.283) (1.100) (1.100) (1.100) (1.500) (1.500) (1.500) (1.900) (1.900) (1.900) (2.283) (2.283) (2.283) (2.283) (1.100) (1.500) (1.500) (1.500) (1.900) (1.900) (1.900) (2.283) (2.283) (2.283) (1.100) (1.500) (1.900) (1.900) (2.283) (2.283) (2.283) (1.500) (1.900) (2.283) (1.900) (2.283) (2.283) (2.283) d L±1 H±2 12 (0.472) 22 (0.866) 16 (0.630) 24 (0.945) 18 (0.709) 26 (1.024) 20 (0.787) 30 (1.180) 24 (0.945) 37 (1.457) 31 (1.221) 58.5 (2.303) 40 (1.575) 12 12 12 12 12 12 12 12 12 15 15 15 15 12 12 12 12 12 12 12 15 15 15 12 12 12 12 15 15 15 12 12 15 12 15 15 15 (0.472) (0.472) (0.472) (0.472) (0.472) (0.472) (0.472) (0.472) (0.472) (0.591) (0.591) (0.591) (0.591) (0.472) (0.472) (0.472) (0.472) (0.472) (0.472) (0.472) (0.591) (0.591) (0.591) (0.472) (0.472) (0.472) (0.472) (0.591) (0.591) (0.591) (0.472) (0.472) (0.591) (0.472) (0.591) (0.591) (0.591) -Other tolerance on capacitance value: please consult us 3 High Voltage Ceramic Capacitors Type HP/HW – Strontium-based Dielectric HW RANGE: UNCOATED DEVICES REFERENCES – VOLTAGE AND CAPACITANCE RANGE ø d Handling of uncoated devices must be done under strict cleanliness conditions.
